Abstract:V letih 2007 in 2008 smo na kmetiji Vrecl v Zgornjih Hočah (325 m n.v., 46o 29' 31'' s.g.š., 15o 37' 13'' v.g.d.), na travinju združbe Lolietum, ugotavljali spremembo pH vrednosti tal v odvisnosti od gnojenja z živinskimi gnojili. V poskusih (naključni bloki v štirih ponovitvah) smo uporabili dve različni količini gnojevke (obravnavanje 1= gnojevka velike količine (2,5 GVŽ ha-1) in 48 kg P2O5 (gnojilo hiperkorn), obravnavanje 2 =gnojevka manjše količine (1,9 GVŽ/ha) in 41 kg P2O5 (gnojilo hiperkorn)) in za primerjavo NPK (obravnavanje 3 =170 kg ha-1 N, 120 kg ha-1 P2O5, 240 kg ha-1 K2O). Ob začetku izvajanja poskusov je bil pH tal (v 0,1 M KCl) 6,15. Po dveh letih izvajanja poskusov ni bilo statistično značilnih razlik v reakciji tal med obravnavanji. Glede na rezultate drugih avtorjev lahko pričakujemo, da bo gnojevka izrazito spremenila reakcijo v smeri nevtralizacije na zelo kislih ali alkalnih tleh.

Title:Impact of animal manure on the soil pH
Abstract:In the Vrecl farm at Zgornje Hoče (325 m a.s.l., 46° 29’ 31” N, 15° 37’ 13” L), in the years of 2007 and 2008 we studied the impact of animal manuring on the soil pH of grassland of Lolietum multiflorae community The experiment was designed as randomized blocks with four replications: treatment 1- fertilization with slurry (2.5 AU and 48 kg P2O5 ha-1(fertilizer hypercorn)); treatment 2- fertilization with slurry (1.9 AU and 41 kg P2O5 ha-1 (fertilizer hypercorn)); treatment 3 – NPK mineral fertilizer (170 kg ha-1 N, 120 kg ha-1 P2O5, 240 kg ha-1 K2O). At the beginning of the experiment the soil pH amounted to 6.15. At the end of experiment no statistically significant differences in pH values were observed. Considering the results found in literature it can be expected that fertilization with slurry may have a bigger impact on the neutralization of soil acidity on the very acid or alkaline soils.
Keywords:soil pH, organic fertilizers, slurry
